Does your company close when you “run out of bread”?

I really like this story of Vinnie’s Sub Shop that closes for the day when that day’s fresh bread is all gone. This translate to nearly all businesses. Do you know your product or service well enough to do what Vinnie’s does and close shop when you can no longer offer the best? This could mean turning down work that’s outside of your core competency or referring such work to a competitor. That takes guts. But in the long run, it’s a smart move because it gains the trust of your most loyal customers.
